javaXUL provides a simple to use XUL implementation, including CSS and JavaScript capabilities, for use in Java projects. Some uses include the embedding of an XUL stack in a Java browser and using XUL as a UI language in Java applications, including the ability to communicate with Java. It is not intended to compete with much more complete RIA offerings such as Flash, Silverlight, or javaFX. Instead it tries to leverage the expressivity of XUL in the Java development area. Compatibility with Mozilla XUL (such as the Firefox implementation) is a goal.

jmxtrans is effectively the missing connector between JMX and whatever logging or graphing package that you can dream up. jmxtrans is very powerful tool that reads JSON configuration files specifying servers/ports and JMX domains/attributes and then outputs the data in whatever format you want via special "Writer" objects that you can code up yourself. It does this with a very efficient engine design that will scale to querying literally thousands of machines. The core engine is pretty solid and writers are included for cacti/rrdtool, graphite, and stdout.

Executor is a small but perfectly functional Java (1.5 or higher) JAR executable that is used to run programs in shared computer resources like a pool of computers that you and your friends own. Moreover, it can be used as a simple file sharing program: you can access the files of your home computer from your office computer.
Executor uses a shared or synchronized file system. The user creates a task in one computer (just by uploading a file), and another computer that has the required program will execute the task.
